A vehicle wheel cover noise testing machine comprises a test wheel mounted for rotation in the compartment of a first housing. A wheel cover is attached to the test wheel. A drive wheel is mounted in the compartment of a second housing. The housings are supported adjacent to one another in a cage and have adjacent walls provided with registering openings. The drive wheel is in frictional peripheral contact with a tire on the test wheel through the openings so that the test wheel may be rotated by the drive wheel. A microphone in the compartment for the test wheel detects wheel cover noise.
